Ksp stands for which term?

• A. Equilibrium constant
• B. Solubility product constant
• C. Dissolution rate constant
• D. Solubility equilibrium coefficient

Answer: (B)

Ksp stands for the solubility product constant. It is the equilibrium constant for the dissolution of a sparingly soluble solid into its ions in solution. For a salt that dissociates as AB(s) ⇌ A⁺(aq) + B⁻(aq), the solubility product is Ksp = [A⁺][B⁻]. If the salt produces different stoichiometric amounts, like CaF₂(s) ⇌ Ca²⁺(aq) + 2 F⁻(aq), then Ksp = [Ca²⁺][F⁻]². This value reflects how soluble the salt is at a given temperature and governs whether precipitation or dissolution will occur under given ion concentrations. It’s a specific type of equilibrium constant, not a dissolution rate constant or a nonstandard term like a solubility equilibrium coefficient.
